A move between two cloud products is mechanically easier than leaving a desktop package, because both sides speak CSV and neither holds data hostage on a local machine. The work shifts from extraction to mapping.
Cloud-to-cloud changes the risk profile
| Data extraction | Often the hardest step | Straightforward CSV export | Downtime | Usually needed | Can run in parallel | Main risk | Losing data in transfer | Mis-mapping account structures | Attachments | Usually local files | Need deliberate bulk download |
Export before you cancel anything
Subscription products restrict export access once a plan lapses. Complete every export while the account is fully active.
- Export chart of accounts, customers, vendors and items.
- Export open invoices and bills as at the cut-off.
- Export the trial balance for the cut-off date.
- Bulk download attachments, which rarely transfer between systems.
- Export tax settings and GST return summaries for reference.
Account mapping deserves the most attention
Two cloud systems will both have a chart of accounts, and they will not agree on grouping. A mechanical import produces a technically valid but unreadable structure.
Map to the structure you actually want to report on rather than mirroring the old one. Setting up a chart of accounts covers the grouping decisions.
Why GST handling is usually the reason
General cloud accounting products treat GST as one tax module among many. For a business whose monthly rhythm is GSTR-1, GSTR-3B and GSTR-2B reconciliation, the depth of that module decides how much manual work remains every month.
Mapping the chart of accounts deliberately
This is where a cloud-to-cloud migration succeeds or quietly fails. A one-to-one import produces a structure that validates but reports badly.
- Export the existing chart with balances at the cut-off.
- Group accounts by how you want to read the P&L, not by how they were created.
- Merge accounts that were only ever split for historical reasons.
- Map each old account to a new one in a written mapping sheet.
- Reconcile group totals after import, not just the overall trial balance.
Keep the mapping sheet. When a figure looks wrong three months later, it is the fastest way to find where a balance went.
Attachments and audit trail
Cloud systems hold more than ledger data. Attachments, comments and change history rarely transfer, and each has a different retention implication.
| Invoice PDFs | No | Bulk download and archive | Bill attachments | No | Bulk download and archive | Comments and notes | No | Export where possible | Change history | No | Screenshot key approvals if material | Bank feed history | No | Export statements separately |
Integrations need re-establishing
Connected services are configured per product. Every one has to be set up again, and some will need new credentials from the provider.
Deciding on the basis of monthly effort
Both products will produce a trial balance. The question worth answering is how many hours a month are spent on work the software should have done: repairing exports, re-keying marketplace sales, chasing reconciliation differences. That number, not the feature list, is what changes after a move.
Timing the move around your billing cycle
Subscription products bill in advance, and a migration that ends days after a renewal wastes a period. Work backwards from the renewal date.
- Note the renewal date and the notice period required.
- Plan the cut-off at least six weeks before renewal.
- Complete exports while the account is fully active.
- Run the overlap month before, not after, cancelling.
- Cancel only once the new system has produced a full return.
Preserving the audit trail across the boundary
Auditors ask how a figure moved from one system to another. Documenting the boundary at the time makes that a short conversation.
Testing with your own data, not the demo set
Trials configured with sample data behave well. Your data is what will expose the gaps.
| Import your real item master | Field limits, HSN handling | Raise your most complex invoice | Discount, multi-rate, freight handling | Enter a purchase with blocked credit | Whether it can be flagged | Generate GSTR-1 from a real month | Whether the JSON is accepted | Run a party ledger | Whether the format suits your customers |
What usually triggers the move
Cloud-to-cloud moves are rarely about price. They are usually about one recurring task that the current product handles awkwardly.
If none of these apply, the case for moving is weak. Migration has a real cost and should solve a named problem.
Running the overlap month properly
Parallel running only works if both systems receive the same transactions. Entering a subset into the new one proves nothing.
- Enter every transaction into both systems for the full month.
- Compare daily totals rather than waiting for month end.
- Reconcile the bank in both and confirm the same closing balance.
- Generate GSTR-1 from both and compare invoice counts and values.
- Investigate every difference before switching off the old system.
After the switch
| First week | Daily billing runs without workarounds | First month | A full GST return filed from the new system | First quarter | Reports match expectations; accountant is comfortable | First year end | Statutory accounts produced without reconstruction |
Frequently asked questions
Can both systems run at once?
Yes, and cloud-to-cloud is where parallel running is easiest. One overlapping month through a full return cycle is the safest way to validate.
What happens to data after cancelling?
Retention periods vary and access is usually read-only or removed. Export everything before cancelling, not after.
Do historical GST returns need migrating?
No. Filed returns live on the GST portal. Keep exported copies for your own records and start fresh from the next period.
