The Future of ERP in 2026: Buy, Extend or Build Your Own?

ERP (enterprise resource planning) means one system of record for the money, stock, orders and people of a company. In 2026 a growing company rarely asks whether it needs one. It asks which parts of its work should run on a ready-made ERP and which parts need software of its own. This guide helps you answer that with real prices and dates.

Three facts frame the decision this year:

• Overruns are still common. Panorama Consulting’s 2026 ERP Report, released on 4 March 2026, found that more than a quarter of organizations went over their project budget, and the top cause was extra technology they needed. Business intelligence was the digital initiative most often deployed in a big way, at 55.3% of organizations (Panorama Consulting, 4 March 2026).
• Old systems have deadlines. SAP provides mainstream maintenance for SAP Business Suite 7 core applications until the end of 2027, then optional extended maintenance until the end of 2030 at a premium of two percentage points on the maintenance basis (SAP Support strategy).
• Cloud ERP is priced per user. Microsoft lists Dynamics 365 Business Central at $80 per user a month for Essentials, $110 for Premium and $8 for Team Members, paid yearly (Microsoft Business Central pricing).

When is it time for an ERP?

Look for these signs in your own company:

• People type the same data into two or more systems.
• Nobody can tell you today’s stock or cash position without a spreadsheet.
• Month-end reports take days of manual work.
• Each department has its own tool, and the tools don’t share data.
• Managers can’t see the numbers away from the office.
• Access to sensitive data is all or nothing.

If three or more are true, you need one system of record. That doesn’t always mean a large ERP suite. Sometimes it means a smaller accounting system plus one piece of software that fills the gap.

Three routes: buy, extend or build

Route	What it means	Fits when	Watch out for
Buy and configure	A ready-made ERP, set up for your company by a partner	Your processes are close to standard: accounting, purchasing, stock, payroll	Per-user fees that grow with the team; paid add-ons and extra modules
Buy the core, build around it	Keep a ready-made ERP or accounting system as the record, and build portals, apps or automations on its API	Most work is standard, but customers, field staff or partners need their own screens	Every integration is code you maintain; API limits and version changes
Build custom	Your own system for the processes that make you different	The process is your product, or per-user pricing breaks your margins	You own upkeep, security and every future change

For most growing companies the middle row is the safe default. Accounting and payroll stay standard, and the part that earns money gets its own software. Build fully custom only when a ready-made system can’t do the job or costs more than the business can carry.

Do the per-user math before you choose

Licence fees look small per person and large per year. Twenty-five people on Business Central Premium at the list price come to 25 × $110 × 12 = $33,000 a year, before implementation, add-ons and partner fees. Microsoft notes that prices vary by country and currency, so get your own quote.

Compare five years of each option, not a licence fee against a build fee. A custom build has hosting, support and changes; a bought ERP has licences, partner days and add-ons. Our guide to total cost of ownership lists the costs people forget on both sides.

The Panorama finding points the same way: extra technology bought mid-project was the top reason budgets broke. Price the integrations, reports and add-ons before you sign, not after.

What the future of ERP looks like from the build side

Three changes show up in our own projects.

AI suggests, a person approves. On IPOPBOOKS, a bookkeeping platform for US small businesses, AI suggests a category for each bank transaction, how sure it is and why. A bookkeeper approves or fixes it, and only then does the entry go into the ledger. The system remembers each approval, so the next charge from the same merchant gets its category with no AI call.

Per-client pricing pushes some companies to build. The IPOPBOOKS founder found that ready-made accounting software would have cost more per client than he planned to charge, so he needed his own platform. We built it with a double-entry ledger, an hourly check that the books still balance and a log of every posted entry. It went live 10 weeks after kickoff.

Paper still comes first. Before SmartBuilding, construction companies tracked dozens of sites in paper journals and copied them by hand into Google Docs. We replaced that with a platform where each role sees only what it should, access requests are electronic, a QR code on each worker’s helmet opens their profile and violations go into a log. The platform was built in 2 months.

None of these replaced an ERP suite. Each one took the process that made the business different and gave it software of its own. That is the middle route from the table: software built around one process and connected to the systems a company already has, which is what our custom software development work covers.

How we would estimate it

Start from processes, not modules. A brief like “bookkeepers approve AI-sorted bank transactions, owners see a profit and loss report” is easier to price than “we need finance and inventory”.

You can get a free project estimate from a brief like that. The estimate turns it into user stories, and you confirm what is in scope, so every hour in the budget traces back to a story you kept. We check the hours the model suggests against what our team actually books on finished projects, then multiply by our published rate of $39-55 an hour. The result is an hours range, a budget range and a number of weeks. It is a planning range, not a fixed quote. Put it next to five years of licence fees and you have a fair comparison.

What we would do

1. Map one process end to end, such as order to cash, with the people who run it.
2. Mark each step as standard or yours.
3. Price the standard part as licences: users × list price × 12, plus a partner quote for setup.
4. Price your part as user stories with an hours range.
5. Build first whatever removes double entry, usually an integration or a portal.
6. Move one department, run old and new side by side for one month-end close, then switch.
7. Keep a log of every posted change from day one.

FAQ

What are the main ERP trends in 2026?

Three matter most to a buyer. Budgets still break: Panorama’s 2026 ERP Report found more than a quarter of organizations went over budget. Business intelligence was the most widely deployed digital initiative, at 55.3%. And older systems face deadlines, such as SAP’s end of mainstream maintenance for Business Suite 7 at the end of 2027.

Should a small company build a custom ERP?

Rarely the whole thing. Keep accounting and payroll on standard software and build only the process that makes you different, or the part where per-user fees break your margins. IPOPBOOKS built its own platform because ready-made software would have cost more per client than it planned to charge.

How much does an ERP cost per user?

Microsoft lists Dynamics 365 Business Central at $80 per user a month for Essentials, $110 for Premium and $8 for Team Members, paid yearly. Implementation, add-ons and partner fees come on top, and prices vary by country.

What happens to SAP ECC after 2027?

SAP’s mainstream maintenance for SAP Business Suite 7 core applications runs until the end of 2027. Optional extended maintenance runs until the end of 2030, at a premium of two percentage points on the maintenance basis.

Can Rocketech connect our ERP to a custom app?

Yes. Building portals, apps and automations on top of an existing system’s API is the middle route in this guide. We price it from user stories at $39-55 an hour.
