CUSTOM SAAS IN 2026: FOR WHOM, AND WHY NOW

Invoicing, orders, shipping, sales follow-up, customer portal: most SMEs stack four subscriptions that do not talk to each other and a spreadsheet that links them. A single tool, written for your way of working, has become affordable.

What changed

Three things. The technical building blocks are mature and free (databases, authentication, payment, email sending). Code assistants speed up the repetitive part. And hosting a tool for ten or fifty users costs a few dozen euros per month. A tool that took six months takes six weeks.

For whom

• The workshop or small manufacturer that manages batches, analyses, multi-parcel shipments and specific invoicing.
• The wholesaler who wants a portal where trade customers order with their prices, their terms, their history.
• The rental business with planning, contracts, deposits and inspections.
• Any company whose central spreadsheet has more than ten tabs.

Who it is not for

If off-the-shelf software does 95% of your need, take it. Custom is for when the remaining 5% costs you hours every week, or when the off-the-shelf software forces its way of working on you.

How to build it without getting it wrong

1. Scoping : we describe your real flows, not the ideal. An order, from arrival to invoice.
2. A first useful release in a few weeks, put in production, used. Not a hundred-page specification.
3. Connections to what exists: POS, accounting, carriers, online store.
4. Operations : hosting, backups, monitoring, evolutions, from €90 per month.

An example

A workshop ERP I run: batch reception with analyses, stock, orders, multi-parcel shipments with carrier labels, invoicing, dashboard. One person uses it all day instead of three programs and a spreadsheet. The case is described in Workshop ERP, and the offer on Custom SaaS.
