RPA or proper API integration?
One drives the screen a person would have used. The other talks to the system directly. They fail very differently.
Use an API wherever one exists, even an awkward one. Reach for RPA only where there is genuinely no programmatic route in, and budget for maintenance.
RPA automates the interface a person would have used: it opens the screen, clicks the fields, types the values. An integration talks to the system underneath. Both move data from A to B, and they differ enormously in how they behave when something changes.
The appeal of RPA is real. It needs no cooperation from the system being automated, which means no vendor conversation, no API licence, and no waiting. For a system with no interface at all, that is genuinely the answer.
How each one fails
The failure mode matters more than the build cost.
RPA breaks on cosmetics
A vendor moves a button, adds a confirmation dialog, or changes a label, and the robot fails — or worse, clicks the wrong thing. Nothing changed functionally, and your automation is down.
RPA fails silently
A well-built integration reports errors. A robot mid-sequence can leave a transaction half-complete in a way nobody notices until reconciliation.
Integrations fail loudly
An API contract change breaks visibly, with an error you can act on. That is a better failure than a robot confidently clicking through a dialog it does not understand.
Integrations need a route in
Their honest limitation: if the system has no API, no database access, and no export, an integration has nothing to connect to.
Check these before choosing RPA
- Does the system have an API, even an old or awkward one? Tally's XML interface counts.
- Is there database access, even read-only?
- Does it support scheduled import or export files? Unglamorous and reliable.
- Is there a supported integration or middleware connector already?
- Is the vendor willing to expose something if asked?
- If all six are genuinely no, RPA is a reasonable answer.
RPA is a workaround for a missing interface. Sometimes a workaround is correct — but price it as one, including the maintenance.
RPA vs API — questions we get asked
Is RPA cheaper to build?
Often, initially. Over a few years the maintenance frequently exceeds the difference, because robots need attention every time a screen changes and nobody warns you in advance.
Can we use RPA temporarily?
Yes, and it is a legitimate tactic — automate now, replace with an integration when a route opens. It works provided the temporary status is written down, because otherwise it becomes permanent by default.
What about AI agents driving software?
The same trade-off with more variability. A model interpreting a screen is more resilient to cosmetic change than scripted RPA and less predictable in what it will do when confused. For anything touching financial records, we would want an API.
The work this leads to
Integrating Tally with the rest of your systems
Tally's XML and ODBC interfaces are awkward but dependable. Wrapped properly, they let your website, CRM, or operations system exchange data with Tally without anyone re-keying.

Zoho apps are individually good and only loosely connected by default. The value is in the flows between them — and in connecting them to what sits outside.

Voice AI or a better IVR?
A well-designed IVR is cheaper, more predictable, and adequate for a surprising share of what businesses try to solve with Voice AI.
ComparisonBuild or buy?
The question is rarely which is cheaper. It is which liability you would rather hold — a vendor's roadmap, or your own maintenance.
