Switching from Wave to FirmWorks
Outgrew Wave’s free tier? Keep the basic invoicing model, get HR/projects/chat/notes/boards in the same workspace, and finally get Thai VAT/withholding tax handled by default.
What you keep
- Invoicing and receipts with line items.
- Customer/contact records that flow onto every document.
- Expense capture with receipt attachments.
What you gain
- Native HR module — employee directory, onboarding checklists, leave with manager approval.
- Projects, tasks, and kanban boards next to invoices, sharing the same contact records.
- Internal chat and a notes/wiki module — replace Slack and Notion alongside the upgrade off Wave.
What’s better
Thai VAT/WHT and Singapore residency on day one
Wave is anchored to US/Canada small businesses — Thai VAT (7%) and Thai withholding tax aren’t first-class fields, and recurring invoices on Wave skip the Thai-specific tax IDs. FirmWorks ships VAT and WHT on every document by default and stores everything in Singapore (ap-southeast-1) instead of US data centres. The trade-off is that Wave’s free tier is genuinely free; FirmWorks’ paid tiers cover all six modules instead of just accounting.
