Move fully
Best if plants, branches or users keep growing and every change waits on a partner
ERPNext becomes the books and the operations from one switch date.

If you have them, also: add‑on screens.
Three ways off SAP Business One
Moving everything at once isn't always right.
Move in phases
Best if one company or plant can go first, or the books should switch at a year start
One company goes live and ties out; the others follow on the same setup.
Stay on SAP Business One, with our support
Best if B1 works and what hurts is a report, an add‑on or an integration
We fix those around your B1. We don't sell SAP licences.
Switch only when it ties out
Map your B1
Companies, accounts, partners, stock, add‑ons and user‑defined fields, in a written plan that says what moves, what is rebuilt and what stays archived.
Load, then tie out
A test load checked against your SAP trial balance, ageing and stock value, with your accountant, until it matches.
Switch before the renewal
On a month start or 1 April. B1 goes read‑only; your team is trained on your own data, and we sit in on the first month‑end.
Our ERPNext projects went live in 9 to 12 weeks a site (Fixcent, Rosemount, a nine‑plant manufacturer off SAP Business One, Splendx; 2026). Your timeline is in the written plan. Moving off SAP ECC or S/4 instead? SAP to ERPNext.
See it after the move
Real ERPNext screens with a guide on each step. No sign-up, no card, no account.
Made to order
A sales order becomes a work order; material is issued, made and costed.
Stock moves to another branch
Stock goes to a branch, and each warehouse shows its own stock on one report.
The owner's morning check
Sales, cash and stock on one screen, sliced by branch, with what needs you today.
Your questions, before you move
No. Masters, open items and opening balances move and are tied out to your SAP trial balance and stock value before you switch. Closed years stay readable, in B1 itself or in a full export you keep, so nothing is deleted. You import the years you still report on.
Each one is listed in the plan and decided on its own: user-defined fields and tables become ERPNext custom fields and forms, approval procedures become workflows, Crystal layouts become print formats, and add-ons become an ERPNext feature, the India Compliance app or a small app. Some turn out to be unused and are dropped.
Only for how we read the data. Either way we work from read-only access or exports agreed with your IT team or SAP partner in the first week, and the tie-out is the same. Nothing is written back to your SAP database, and B1 keeps running until the switch.
Before your next maintenance renewal, on a month start or 1 April for the books. Our projects went live in 9 to 12 weeks a site, so start about three months ahead. There is no forced deadline: SAP lists Business One 10.0 in mainstream maintenance until 31 December 2028.
Yes. GSTINs, HSN codes and tax templates move with the masters, and e-invoicing and e-way bills are set up in ERPNext and tested on real invoices before the switch. Returns for periods filed from SAP stay as filed; ERPNext produces them from the first live document after the switch.
Our ERPNext projects went live in 9 to 12 weeks a site in 2026, including a nine-plant manufacturer off SAP Business One in 11 weeks. The data move is one part of that, set by companies, years, add-ons and user-defined fields. You get the timeline in a written plan.
It depends on companies, users, years of history, add-ons and what else goes live. What an implementation costs explains what moves the number; after a call you get a written scope to compare with your SAP renewal. ERPNext itself has no licence or yearly maintenance fee.
Yes. If B1 works and what hurts is a report, an add-on or an integration, we fix those around it. We don't sell SAP licences or act as your SAP partner; we support the system you run. If you move, B1 or a full export stays as the read-only archive.
Some. Accounts, items and partners carry over, so the records look familiar; screens and reports move from the B1 client to the browser. Key users are trained on your own data before the switch, and we sit in on the first month-end close.
