iCaps Replacement
Jems: the modern replacement for iCaps.
Move off iCaps without losing a thing. Jems does everything iCaps does day to day and a good deal more, all in the cloud and reachable from anywhere, and your data and full history come across in one fixed-price migration we built and tested on real iCaps systems.
In short
Jems is a UK-built cloud ERP designed as a modern replacement for iCaps. It covers everything you run iCaps for, from stock control, purchasing and manufacturing orders to MRP and free issue, and adds a live shop floor, whole-team pricing and access from anywhere. Moving across is a fixed, all-in price that brings all your data and history with you, rehearsed on your real data before you commit.
Capability for Capability
Everything iCaps does, and more
If you run it in iCaps today, you run it in Jems. Here is how each part of iCaps maps across, with the modern additions iCaps does not offer.
New in Jems, beyond iCaps
Cloud-native
Runs in the browser. No server to buy, no backups or VPNs to manage, and access from anywhere.
Free issue
Handle customer-supplied material end to end: receive it by purchase order to the customer or as a consignment delivery, keep each customer's stock segregated, set per-customer profiles, and apply handling fees on quotes.
A live shop floor
Jems Make adds worker clock-in/out, QR-scanned job tracking, and live progress and holds.
Live job costing
Actual versus standard cost on every works order, while the job is still running.
Performance KPIs
Variance by worker, operation and department, with trends and CSV export.
UK-built and supported
VAT, nominal codes and sterling handled natively, supported by the team that builds Jems.
Why Manufacturers Switch
Why iCaps users move to Jems
Modern ERP, not a legacy system
A clean, browser-based system designed for how factories run today, in place of older on-premise software, so new staff get up to speed quickly.
Actively supported and developed
Jems is under active development, with regular improvements and UK support from the team that builds it, so your software keeps getting better.
Cloud-based and secure
No ageing on-site server or old Windows machine to keep alive, patch or back up. Reach Jems securely from anywhere.
Connected to your tools
Live supplier pricing and stock checks are built in today, and two-way accounting sync with Xero, QuickBooks and Sage arrives Q3 2026.
A predictable migration
One fixed, all-in migration price and a rehearsal on your real data before you commit, so the outcome and the cost are clear up front.
Your data stays yours
No lock-in. A contractual export promise gives you everything, in standard formats, any time you ask.
Built with iCaps users
Tested on real iCaps systems
Two UK SME manufacturers running iCaps helped shape Jems and its automated iCaps migration, rehearsed against their live systems. The result is a migration path purpose-built for iCaps, not a generic importer.
Switching from iCaps
Your iCaps data and history, brought across
ERP migrations fail on risk, not software. Jems removes the risk in stages, and you stay in control of the trigger. Your iCaps system is never switched off until you are live in Jems.
The Safe Switch Promise
The risk of switching is ours, not yours.
We migrate your real iCaps data into Jems and run it alongside your current system. Your old system stays live throughout, and you pay only a deposit to start: the balance isn't due until you've checked every record and confirmed it's right. If anything's wrong, we keep working until it isn't.
Free data assessment
We review your iCaps system and confirm exactly what comes across.
Rehearsal migration
Your real iCaps data in a Jems staging system. Test side by side for as long as you like.
You pick the date
Nothing happens until you say go. Your iCaps system keeps running.
Rapid cutover
Final data handover to a validated go-live, on the date you choose.
Hypercare month
30 days of priority support while your team settles in.
Migration Pricing
One all-in price for the move from iCaps.
Every year of history, full ledger, every trace record. Included. No hidden extras, no per-table charges.

Common Questions
Replacing iCaps with Jems: your questions
Is Jems a good replacement for iCaps?
Jems is a UK-built cloud ERP designed as a modern replacement for iCaps. It covers everything you run iCaps for, from stock control, purchasing and manufacturing orders to MRP and free issue, and adds a live shop floor, whole-team pricing and access from anywhere.
Does Jems do everything iCaps does?
Across the day-to-day, yes: stock control, purchasing, manufacturing orders, MRP, parts and BOMs, free issue, reporting and accounts handover all have a direct equivalent, and Jems adds a live shop floor and more. Drag-and-drop Gantt scheduling is the one area still on the way, arriving Q4 2026.
Does Jems handle free issue and customer-supplied material?
Yes. Jems handles customer-supplied (free-issue) material end to end: receive it against a purchase order to the customer or as a consignment delivery, keep each customer's stock segregated so it is never used on another job, set per-customer default profiles, and apply handling fees on quotes.
Can I move my iCaps data and history to Jems?
Yes. The move is a fixed, all-in price that brings across every year of history, the full ledger and every trace record. Your data is rehearsed in a Jems staging system on your real data before you commit, and it stays yours with a contractual export promise.
How long does it take to migrate from iCaps to Jems?
You take as long as you like to test the rehearsal migration. When you pick a date, the cutover is usually quick, often over a single weekend, and your old system stays live until you are live in Jems, followed by a hypercare month of priority support.
How much does it cost to move from iCaps to Jems?
The move from iCaps is a fixed all-in price of £14,995 + VAT, covering all your data and history. You can pay upfront or spread it over 12 or 24 months.
Is Jems cloud-based?
Yes. Jems runs in the browser, so there is no server to buy or maintain, no backups or VPNs to manage, and you can reach the factory from anywhere.
Will my iCaps system keep running during the move?
Yes. Your iCaps system is never switched off until you are live in Jems, so you can compare the two side by side and only commit when you are ready.
