Planning Software for Manufacturing | What MRP Software Can Do

If you're running a small manufacturing business, MRP planning software can transform how you manage materials, production, and costs. Here's exactly what it does — and why spreadsheets can't keep up.

Planning Software for Manufacturing | What MRP Software Can Do

Running a small manufacturing business means managing a lot of moving parts at once. Materials to reorder. Production runs to schedule. Customer orders coming in across multiple channels. Costs to track before tax time turns into a crisis.

Most makers start by managing all of this in spreadsheets. And for a while, it works. But as order volume grows, spreadsheet-based systems start to show their limits — manual entry errors, stock counts that don’t reflect reality, recipe costs that get stale as material prices change.

That’s the problem manufacturing planning software — more commonly known as MRP software — is built to solve.

This guide covers exactly what MRP planning software does: the features it provides, how each one applies to small-batch manufacturing businesses, and how it compares to managing those same tasks in a spreadsheet.

If you’re looking for the case for why MRP matters for small manufacturers, this overview of MRP systems covers five key reasons.

What is MRP planning software?

MRP software stands for Manufacturing Resource Planning software. It’s a system designed to help manufacturing businesses manage their materials, production schedules, and costs in one connected place.

In the past, MRP software meant enterprise-level tools built for large factories with complex production lines — think Sage or NetSuite. These days, there are purpose-built MRP solutions scaled for small and medium-sized manufacturers. Whether you’re making candles, soap, jewellery, or skincare products, there’s software designed specifically for how you work.

Where MRP software differs from a generic inventory app is in how everything connects. Your material stock levels feed into your production runs. Your production runs update your finished goods inventory. Your finished goods inventory flows through to your order fulfilment. Everything talks to everything else — so you’re not manually reconciling numbers across three different spreadsheets.

Spreadsheet vs. MRP software: what’s actually different?

Before getting into the features, it helps to see exactly where spreadsheets fall short compared to purpose-built planning software:

TaskIn a spreadsheetWith MRP software
Check current stockManual count or formula lookupLive dashboard, updated automatically
Cost a recipeManually enter material quantities × pricesAutomatic calculation from bill of materials
Update costs when a material price changesManually update every recipe that uses itAutomatic — one price update cascades everywhere
Track what you can make with current stockComplex formulas, easy to get wrongInstant max-manufacture calculation
Assign production runs to staffSeparate tracking system or sticky notesBuilt-in manufacturing orders
Calculate COGS for taxHours of manual workPull a report
Know when to reorder materialsRequires constant monitoringLow-stock alerts and reorder thresholds
Track orders across Etsy + ShopifyTwo separate tabs at minimumAutomatic sync from each channel

The difference isn’t just convenience. Each of those gaps is a place where errors creep in, costs get underestimated, or decisions get made without accurate data.

What can MRP planning software do for your manufacturing business?

1. Real-time material inventory tracking

The foundation of any MRP system is knowing exactly what you have on hand — not what you had last week when you did a manual count.

With MRP software, every time you record a production run, the materials you used are automatically deducted from your inventory. Every time you receive a delivery, stock levels update immediately. The result is a live picture of what’s on your shelf at any moment.

For a candle maker managing ten different fragrance oils, three types of wax, and multiple wick sizes, that live inventory is critical. Running out of fragrance oil mid-batch doesn’t just waste wax — it delays the entire production run and potentially pushes customer orders back.

MRP software also lets you set reorder thresholds for each material. When wax drops below a certain level, you get an alert — or the system automatically generates a purchase order — long before you’d actually run out. That’s the difference between proactive restocking and scrambling.

2. Bill of materials and recipe costing

A bill of materials (BOM) is the recipe for your product — every ingredient, component, or material, with the exact quantity used per unit or batch.

MRP software lets you build BOM records for each product, then uses those records to:

  • Calculate exactly how much each product costs to make (automatically updated when material prices change)
  • Show how many units you can produce from materials currently in stock
  • Generate pick lists for production runs so your team knows what to pull

The costing piece is where many makers discover they’ve been underpricing. A soap maker who buys lye, oils, fragrance, and packaging across four different suppliers might estimate their cost per bar at $2.50. When they build a BOM in MRP software and track actual material costs over a few months, they often find their real cost is closer to $3.80 — once you account for waste, yield variation, and all the smaller materials that didn’t make it into the original estimate.

With MRP software, your recipe costs update automatically whenever you record a new purchase price for a material. You always know your current margins, not your margins from six months ago.

3. Production scheduling and manufacturing orders

A production schedule is your plan for what gets made, when, and in what sequence. MRP software makes this manageable.

When an order comes in, you can create a manufacturing order (MO) that:

  • Specifies which product to make and how many units
  • Lists the exact materials needed (pulled from your BOM)
  • Checks whether you have enough stock to start
  • Assigns the run to a team member or production date
  • Tracks progress through the production process

For a jewellery maker doing custom orders alongside standard collection pieces, this kind of scheduling visibility is the difference between a smooth week and a chaotic one. You can see at a glance which orders are in production, which are waiting on materials, and which are ready to ship — without chasing anyone for an update.

Production scheduling software also helps you catch potential problems before they happen. If you have three orders all needing the same chain by Friday and only enough stock for two, you’ll see that conflict on Monday — not Thursday night.

4. Order management and demand tracking

Most MRP software for small manufacturers connects directly to the channels you sell through — Etsy, Shopify, Amazon, and others. Orders sync automatically rather than requiring manual entry.

Once orders are in the system, you can:

  • Track each order’s status through production and fulfilment
  • Set target completion dates and monitor whether you’re on track
  • See which products are selling fastest and plan production accordingly
  • Group orders by product to batch production runs more efficiently

For a maker selling across Etsy and Shopify simultaneously, this means one place to manage everything. No more checking two platforms and maintaining a separate fulfilment spreadsheet — or missing an order because it came in through a channel you hadn’t checked.

Demand tracking over time also helps you forecast. If your beeswax candles reliably triple in sales volume every October through December, you can use that data to front-load your material ordering in September — rather than scrambling to restock in the middle of your busiest period.

5. Cost tracking and COGS reporting

Cost of goods sold (COGS) is what it actually cost you to produce the items you sold. It directly affects your gross profit — and it’s what the IRS wants to see at tax time.

In a spreadsheet, calculating COGS means pulling purchase records, applying them against sales data, and doing a lot of manual reconciliation. Most makers either skip it or end up with estimates that don’t hold up.

MRP software tracks COGS automatically as you go. Because it knows the cost of every material in your BOM, and it records every production run against those costs, it can generate accurate COGS reports for any time period.

Come tax time, instead of hours spent reconstructing costs from receipts and order histories, you pull a report. For many makers, that single feature alone justifies the monthly subscription cost.

Beyond tax time, real-time cost tracking helps you make better pricing decisions throughout the year. If your raw material costs have crept up 15% over the past quarter, you’ll see that reflected in your margins before it becomes a problem — not after.

6. Supply chain and reorder management

Raw material availability is what keeps production running. MRP software helps you stay on top of your supply chain without constant manual monitoring.

Key features include:

Reorder thresholds: set a minimum stock level for each material. When inventory drops below that level, you get an alert.

Supplier lead times: track how long each supplier typically takes to fulfil an order. The system can factor this into your reorder timing — alerting you to reorder before you actually need the material, not after you’ve run out.

Purchase order tracking: record incoming deliveries against purchase orders so stock levels update accurately.

Low-stock visibility across all materials: see at a glance which materials are running low, rather than discovering it mid-production run.

For a bath product maker sourcing shea butter, essential oils, sodium hydroxide, and packaging from different suppliers — each with different lead times — this kind of supply chain visibility isn’t just convenient. It’s what keeps production from stalling.

How to evaluate MRP planning software for a small manufacturing business

Not all MRP software is built for small-batch makers. Most enterprise options assume large production volumes, complex team structures, and IT support to manage implementation.

When evaluating options for a small manufacturing business, look for:

Made-for-makers pricing: enterprise MRP starts at thousands per month. Small-business solutions like Craftybase are priced to make sense for sole traders and small teams.

E-commerce integrations: if you sell on Etsy, Shopify, or Amazon, make sure the software connects directly so orders sync automatically.

Bill of materials depth: can it handle multi-level BOMs? (Products made from sub-assemblies, which are in turn made from raw materials.) This matters if your products have any component complexity.

COGS and tax reporting: built-in COGS reporting saves makers hours at tax time. Check that it’s included as a core feature, not locked behind a higher plan.

Mobile access: if you’re on the shop floor or at a market, can you check stock or log production from your phone?

Support and onboarding: the initial data entry (loading your materials, recipes, and products) is the steepest part of getting started. Good support during that phase makes a significant difference.

Frequently Asked Questions

What is MRP planning software and who is it for?

MRP planning software — short for Manufacturing Resource Planning — is a system that helps businesses manage materials, production, and costs in one connected place. While it was originally designed for large manufacturers, there are now purpose-built MRP solutions for small-batch makers: candle businesses, soap makers, jewellery designers, skincare producers, and anyone else who makes physical products from raw materials. If you're tracking inventory, managing recipes, scheduling production, or calculating COGS, MRP software is built for you.

Can I use MRP software if I'm a one-person business?

Yes — and many solo makers get more value from it than larger businesses, because the time savings hit harder when you're doing everything yourself. Small-business MRP software like Craftybase is designed for sole traders and small teams. You don't need IT support to set it up, and the pricing is built for businesses that don't have enterprise budgets. The main investment is the initial setup: loading your materials, building your recipes, and connecting your sales channels. After that, most of the ongoing work happens automatically.

What's the difference between MRP software and inventory management software?

Inventory management software tracks what you have on hand — stock levels, locations, and reorder points. MRP software goes further: it connects your inventory to your production process, so it understands that making one batch of soap uses specific quantities of lye, oils, and fragrance, and automatically updates stock levels when that batch is recorded. It also handles production scheduling, bill of materials costing, and COGS reporting — things a basic inventory app doesn't cover. For businesses that manufacture products, MRP software is the more complete solution.

How does MRP software help with COGS and tax reporting?

Because MRP software tracks the exact cost of every material in your bill of materials — and records every production run against those costs — it can calculate your cost of goods sold (COGS) automatically over any time period. Instead of manually reconstructing costs at tax time from purchase receipts and order histories, you pull a report. Craftybase includes COGS reporting as a core feature, making Schedule C preparation significantly less painful for small manufacturers who sell DTC.

Does MRP software work with Etsy and Shopify?

Small-business MRP solutions like Craftybase connect directly to Etsy, Shopify, and other platforms. Orders sync automatically — no manual entry required. This means your inventory levels, production queue, and fulfilment status all update as orders come in, regardless of which channel they came from. If you sell through multiple channels, this integration alone can save 30–60 minutes a day compared to manually reconciling orders across multiple dashboards.
