What CA Firms Need From Billing Software
A practice has requirements a single business does not: many GSTINs, several people touching the same records, and a need to hand data to whatever the client already uses. Written by a vendor — the questions apply to us too.

Multiple clients under one account
The first practical question is whether the software treats a second GSTIN as a second business or a second subscription. For a practice that difference compounds fast.
- Can you hold many GSTINs under one login, each with its own numbering?
- Are documents scoped so one client's data cannot appear on another's invoice?
- Do usage limits apply per client or across the whole account?
People and permissions
Juniors, seniors and partners should not all have the same access, and 'we just trust everyone' stops being an answer as a practice grows.
- Does each person get their own login rather than sharing one?
- Can permissions be set per feature, not just per role?
- Are those permissions enforced server-side?
- Is there an audit log of who changed what?
Return data you can actually work from
The value to a practice is in what comes out at filing time. Data assembled from the billing records themselves avoids the reconciliation work that a re-keyed copy creates.
- GSTR-1 export straight from invoices?
- GSTR-3B summaries?
- Reconciliation against GSTR-2B for input credit?
- E-invoicing and e-way bills where clients need them?
Fitting the client's existing setup
Clients arrive with what they already use. Software that insists everything move at once tends not to get adopted.
- Tally-compatible export for clients whose accounts live there?
- CSV and Excel import for onboarding existing records?
- An API for anything you have built yourself?
Where we stand
WeSaveTax supports multiple billing profiles under one login with shared customer records, role-based team access with server-enforced per-feature permissions, edit history on documents and an account audit log on the plans that include it, GSTR-1 and GSTR-3B data from billing records, and Tally-compatible XML export on higher plans.
It handles the billing and receivables side. It is not a practice-management system and does not do your clients' accounting.
