The core differentiator

One company. Three capabilities.

Why SizLix is different: the software is designed by a Chartered Accountant who codes, not by developers guessing at accounting rules.

01 / Foundation

Accounting depth

We understand Indian accounting and tax from the inside: GSTR-1 vs 3B reconciliations, 2B ITC mismatches, TDS section rates, and the real bottlenecks inside busy finance teams. That knowledge goes straight into the software.

Rules we build around:
GSTIncome-tax ActTDSInd AS
02 / Architecture

Software engineering

Purpose-built products, not templates. Reliable data pipelines, strict validation, no fragile spreadsheet formulas, and reconciliation engines that show you exactly why two numbers don't match.

What we build with:
PythonNext.jsPostgreSQLAPIs & webhooks
03 / Future-proof

AI & automation

Practical automation, not buzzwords. We connect disconnected systems, read messy vendor PDFs with OCR, automate multi-step bank matching, and remove the drag of manual data entry.

What changes

From spreadsheet chaos to an automated money trail

This is what order-to-bank reconciliation typically looks like for an online store, before and after it's automated. It's an illustrative example, not a client story.

The manual way (before) Every week, by hand

The finance team juggles several Excel exports every Monday. Formulas break, settlement fees go unchecked, and missing charges slip through.

  1. 1Shopify CSV exports too big to open comfortably in Excel
  2. 2Razorpay, Cashfree and PayU settlement sheets downloaded one by one
  3. 3Days of INDEX/MATCH formulas across order IDs
  4. 4Refunds, chargebacks and gateway-fee GST errors go unnoticed

Outcome:Month-end stress, delayed audit sign-offs, and ledger differences nobody can explain.

The SizLix pipeline (after) Runs on a schedule

A ledger worker that connects your store and gateway data to your bank statement, and reconciles the maths automatically.

  1. Shopify orders captured with gross value and tax lines
  2. Gateway settlements fetched with UTR numbers; fee and GST checked on each one
  3. The bank statement confirms the net credit, down to the rupee
  4. Journal entries prepared in a batch, ready for Tally or your ERP

Outcome:Only the mismatches reach a person, in an exception queue with the context attached.

Time Weekly chore → scheduled run

Reconciliation stops being somebody's Monday.

Leakage Every gap surfaced

Gateway fee, refund and settlement differences are flagged, not buried in a sheet.

Audit trail Every match traceable

Each entry links back to the order, settlement and bank line it came from.

Engineering services

Tell us what your team does manually.
We'll figure out what can be automated.

We look for the repetitive work: wherever people download, copy, paste, compare, reconcile, classify, calculate or report the same numbers again and again.

Bank automation

Stop logging into every banking portal each morning. We build scheduled statement pulls, parsing rules for messy narration strings, and automatic mapping to customer and vendor ledgers.

Statements → Parsing → Rule engine → Tally / ERP

GST automation

Continuous 2B vs purchase register matching. Missing vendor invoices flagged early, reminders sent to vendors by email or WhatsApp, and ITC claimed by rule.

Purchase book ↔ GSTR-2B → Vendor reminders

Document & invoice OCR

Line items pulled from multi-page scanned bills, bills of entry, transport LRs and other unstructured PDFs, straight into structured tables.

PDFs / scans → OCR + AI → Validated data

Large-scale reconciliation

Big transaction logs matched against gateway reports, warehouse dumps and inventory records, using rule-based logic you can audit line by line.

Large exports → Rule-based matching → Exceptions only

WhatsApp & communication

Automated financial messages on WhatsApp: customer ledger statements, payment reminders, receipts and operational alerts.

Ledger event → WhatsApp API → Customer

AI review agents

Agents set up with your accounting policies that review journal entries, spot tax classification errors and flag out-of-policy spending, for a person to approve.

Continuous policy check → Flag for review

What can we automate in your team?

Pick a common bottleneck to see the blueprint SizLix uses to replace the manual work.

Blueprint: bank feeds

Bank statement automation, without manual entry

We replace the daily chore of downloading CSVs and PDFs from banking portals. Narration strings are parsed with deterministic rules first, and fuzzy matching only where the rules run out.

  • Step 1: Daily statement pull, through the bank's API where one exists or from statement files
  • Step 2: UPI references, NEFT/RTGS details and sender names parsed from narrations
  • Step 3: Receipt, payment and contra vouchers prepared for Tally or your ERP

Our engineering philosophy

Why does a Chartered Accountant build software?

Because after working with businesses long enough, you see the same problem everywhere:

“Bright, capable finance and operations people spending hours every week downloading CSVs, matching spreadsheets, chasing vendor GST credits and typing numbers into software.”

The problem isn't effort. It's the lack of connected, engineered systems. Developers build software from specs they don't fully understand; accountants know the rules but rarely write the code that enforces them.

SizLix was founded on a simple conviction: if an accounting rule can be defined, it can be engineered. We don't just know the rules — we build the machines that apply them.
