ERP, off-the-shelf or custom software: what should a small manufacturer choose?

What most small manufacturers actually use

In the small manufacturers we meet, the picture looks the same. Invoicing runs through accounting software: Sage 50 (formerly Simply Accounting), Acomba or QuickBooks. That same software often serves as the customer list, for lack of a CRM. Proposals are prepared in Excel or Word, changes arrive by email, and the status of each order lives on a whiteboard or in the heads of two or three people.

It works, until volume grows. An option copied wrong becomes a production error. Sales calls the plant to find out where an order stands. The same information is typed three times, from the proposal to the work order, then to the invoice. Our page on replacing Excel with an application describes the signs that a file has become the team’s system.

That was the situation at Pavar, which builds chairs and banquettes for restaurants across North America: no ERP, no CRM, accounting software, and proposals prepared in Excel with hundreds of possible choices.

The three possible paths

An ERP, or enterprise resource planning system, brings sales, purchasing, inventory, production and accounting together in a single system. Production software, also called MRP (manufacturing resource planning), is limited to planning, bills of materials and manufacturing orders, alongside your accounting. A custom application follows your own steps and connects to the accounting software you already use.

The first criterion is how you produce. A plant that builds in series or in continuous runs follows steps that off-the-shelf software knows well. A plant that builds to order, with products configured for each customer, has steps of its own: that is where standard software forces the most compromises.

The main software, compared

Here is what the vendors publish themselves, read on their sites on October 12, 2026, and our view of the kind of business each one suits. Prices are in Canadian dollars, per user per month, unless stated otherwise. They change often: check them before you decide.

If you already use Acomba, two options plug into it: ServiCentre ERP 360, which offers a Manufacturing package, and Acomba’s Production Management module, listed at $55 a month, which handles manufacturing recipes. Other Quebec vendors are worth a look, for example SEIGMA, integrated management software for small businesses, and DCi Software, in Vaudreuil-Dorion, for manufacturing management. Neither publishes prices.

The real cost of an ERP: changing the way you work

An ERP is built around a standard way of selling, buying and manufacturing. Implementing one means configuring it, moving in your customers, products and bills of materials, training the team, and above all adapting your methods to its own. That last part is the one most often underestimated.

A manufacturer we are meeting with right now has just implemented an ERP. The team is seeing the effort it takes: understanding the software, then adjusting their way of working so it fits. The software is not at fault. It is the normal price of a tool built for the average business.

Another point to plan for: most ERPs replace your accounting. Genius ERP and Prextra, for example, have their own accounting module. Leaving Sage 50, Acomba or QuickBooks also affects your accountant and your month-end habits.

For a plant with typical steps that wants a single system and accepts adapting to it, an ERP remains a good choice. We will tell you if that is your case.

When custom software is the better choice

• Your products are configured: models, dimensions, fabrics, finishes, hardware, and every choice changes what the plant builds.
• The proposal has to become a work order without anyone retyping the information.
• Your customers take part: they approve the proposal, then specify their choices online.
• You track every order step by step, and sales needs to know where it stands without calling the plant.
• The way you sell or build sets you apart, and you want a tool that strengthens it rather than standardizing it.

Off-the-shelf software does well what all businesses have in common, and less well what is specific to you. If you want to build on your advantage and create a tool unique to your field, custom software is almost always the better option. With one exception: accounting. It has nothing to gain from being reinvented, and your accounting software already does it well.

Pros and cons of each option

No option is risk-free. Here are the risks we see, including those of custom software, and how to reduce them.

The model we build, step by step

Our approach fits in one sentence: keep your accounting software and build the rest around the way you work. Information is entered once, at the start, then follows the order all the way to the invoice.

That is the path of the application we built for Pavar, in use for several years. Here are three of its screens, recreated with demonstration data.

A proposal that took hours of work in Excel is now prepared in minutes. That is an order of magnitude, not a timed measurement. Maria Iermieri, Vice-President of Sales and Marketing and co-owner, sums it up: “Preparing a proposal used to mean working in Excel. Now our products, the client’s choices and the details of their order all live in the application. We save time, and we move forward with far less risk of error.” In our projects, the code and the data belong to the client.

How to decide: six questions

The answers rarely all point the same way. Start with the step that costs you the most time or errors: that is the one that should drive the choice. For criteria that apply beyond the plant, see our guide custom or off-the-shelf software.

The features to check, whichever path you take

ERP, production software or custom application: these features come up in almost every plant. Check which ones you need, and how each option handles them.

• Products and bills of materials: your models, their options, the materials and the manufacturing steps of each.
• Planning: the order of jobs on the floor, based on promised dates and real capacity.
• Production tracking: the step each order is at, visible to sales and to the plant alike.
• Traceability: lots and serial numbers, if your customers or your industry require them.
• Cost of goods: what an order actually cost in materials and labour.
• Links with your tools: accounting (Sage 50, Acomba, QuickBooks), design (SolidWorks, Inventor) and, for large customers, electronic data interchange (EDI).
• Your data: the ability to get it back complete, in a common format, the day you change tools.

How much does a custom application for a plant cost?

The price depends on the number of screens, the rules to program and the integrations with your tools. It is set per project, in the proposal, before work begins. A first working version is ready in about eight weeks: we start with the step that wastes the most time, then add the others. Our guide on the cost of a custom application details what drives the price.

Compare over several years. An ERP is paid per user, every month, plus implementation. A custom application is paid mostly up front, then in hosting, support and improvements. The right calculation depends on how many people will use the tool and how much your own steps matter.

Government funding: what actually applies

Investissement Québec’s ESSOR program funds the diagnosis and the digital plan (component 1B, up to 50% and $20,000) and then carrying it out (component 1C, up to 50% and $50,000), as a non-repayable contribution. It targets businesses with 250 employees or fewer and revenue of at least $2.5 million. The eligible expenses listed are mainly fees for outside consultants, and the program ends on March 31, 2027.

Quebec’s investment and innovation tax credit (C3i) covers the purchase of an eligible “management software package”: 15% in Montreal and Quebec City, up to 25% in some regions, for expenses incurred before January 1, 2030. The text targets a software package: for custom-built software, have your tax advisor confirm eligibility. Canada Economic Development for Quebec Regions also offers an interest-free repayable contribution, generally up to 50%, for adopting systems such as an ERP. When training the team stems from a new technology, Services Québec’s MFOR program can cover up to 65% of it.

Some vendors state that Investissement Québec can cover up to 40% of implementation costs, and firms that specialize in grants put these applications together. The rules change often: have your project confirmed before counting on any funding.
