Solution for businesses that have outgrown spreadsheets
Excel to ERP migration, one spreadsheet at a time
Excel got you here. Stock, orders, customer dues, payroll, costing — each in a workbook someone built years ago and nobody dares to change. AutoProbaho migrates businesses from Excel to an ERP in stages: we understand what each sheet really does, clean and move the data, replace the sheet with a proper module, and only retire the spreadsheet when the team trusts the system. No big-bang cut-over, no lost history.
The spreadsheets work — until two people need the same file
The signs are familiar: several versions of the same workbook, formulas nobody understands, VLOOKUPs that break when a column moves, files that are too big to open on a phone, and a monthly panic when the one person who maintains the master sheet is on leave. Data is re-typed from one sheet to another, so stock, sales and accounts slowly drift apart.
Moving to an ERP is the obvious answer, but many attempts fail because the migration is treated as a software installation instead of a data and process project. Dirty master data is imported as-is, sheets are switched off before the module works, and staff keep a shadow Excel because the new system does not do what their sheet did. A staged migration avoids exactly these failures.
Who this is for
- SMEs running stock, sales, purchases or payroll in Excel or Google Sheets and feeling the strain
- Companies with one or two indispensable people who alone understand the master workbook
- Businesses planning an ERP and worried about losing years of history in spreadsheets
- Teams that tried an ERP once and went back to Excel because the switch was too abrupt
Current pain points
Version chaos
'Final_v3_updated' files sent by WhatsApp; nobody is sure which one is current.
Single points of failure
One person knows how the sheet works; if they leave, the business loses its memory.
Data drifts apart
Stock, sales and accounts are typed separately and never fully agree.
No permissions or audit
Anyone with the file can change any cell; nobody can see who changed what.
Fear of the switch
Teams resist because past migrations lost data or the new system did less than the sheet.
What AutoProbaho builds
A spreadsheet inventory and migration plan
Every workbook is catalogued: what it tracks, who owns it, what feeds it, what depends on it — and the order in which to replace them.
Data cleaning and mapping
Item, customer, supplier and employee masters are de-duplicated, standardised and mapped to the ERP model before import.
ERP modules that replace sheets one by one
Each module is built to cover what the sheet actually did — including the odd columns — then the sheet is retired.
Migration tooling
Repeatable import scripts with validation reports, so trial loads can run many times before the final cut-over.
Parallel run and hand-over
The sheet and the module run side by side for a defined period; differences are reconciled until the team trusts the system.
Modules & capabilities
Master data
Items/SKUs, customers, suppliers, employees, chart of accounts — cleaned, coded and owned.
Inventory
Opening stock by location and batch, movements, min/max, replacing stock registers and count sheets.
Sales & receivables
Customer orders, invoices, dues and ageing, replacing sales books and dealer ledgers.
Purchasing & payables
Purchase orders, receipts, supplier bills, replacing purchase registers.
Production or job costing
BOMs, work orders, costing sheets moved into structured records where relevant.
HR & payroll inputs
Employee master, attendance and salary sheets migrated into a controlled module.
Reports & dashboards
The reports management used to build from Excel, generated automatically from the ERP.
Import & reconciliation tools
Templates, validators and difference reports used during and after migration.
Interactive demonstration
Example workflows
Migrating the stock register
- 1Current stock sheets are analysed: locations, units, batches, hidden columns
- 2Item master is cleaned and codes agreed
- 3Trial import runs and a difference report is reviewed with the store-keeper
- 4Physical count sets the opening balance on cut-over day
- 5Sheet is frozen read-only; all movements are recorded in the ERP
Migrating customer dues
- 1Dealer ledger sheets are consolidated and duplicates merged
- 2Open invoices and payments are reconstructed or entered as opening balances
- 3Customer statements from the ERP are compared to the sheet
- 4Sales team confirms balances with key customers
- 5Collections are recorded in the ERP from cut-over
Retiring a costing workbook
- 1Formulas and inputs of the costing sheet are documented
- 2BOM and cost structures are modelled in the ERP
- 3Recent costings are recalculated and compared
- 4Differences are explained and rules corrected
- 5New quotes are costed in the ERP; the workbook is archived
Integrations
- Excel and Google Sheets import/export
- Accounting software (Tally, QuickBooks, Xero, DATEV export)
- Existing databases and legacy software exports (CSV, Access)
- Google Workspace / Microsoft 365
- Barcode scanners for count and label
- WhatsApp Business & email for notifications
- n8n workflow automation
Implementation process
- 01
Spreadsheet audit
We inventory the workbooks, interview their owners and map how data flows between them.
- 02
Migration roadmap
Modules are sequenced by pain and dependency; typically master data and inventory first.
- 03
Clean & trial-load
Data is cleaned with your team; imports run repeatedly until the validation report is clean.
- 04
Build & parallel-run
Each module goes live alongside its sheet; differences are reconciled daily until stable.
- 05
Cut-over & support
Sheets are frozen, the ERP becomes the record, and we support the first month-end closely.
Expected business outcomes
History preserved
Years of stock, sales and customer data are carried into the ERP, cleaned and searchable.
One current version
Everyone works on the same live record instead of emailed copies.
No single point of failure
Knowledge that lived in one person's workbook is now in a documented system.
Confidence in the switch
Parallel runs and difference reports mean the team sees the numbers agree before the sheet is retired.
Security & ownership
Controlled access replaces open files
Role- and field-level permissions and audit trail on every change — the opposite of a shared workbook.
Data stays yours
Migration runs in your own environment; original files are archived, not discarded.
Backups & rollback
Every trial and final load is backed up; a rollback plan exists for cut-over day.
Frequently asked questions
No. Historical records are cleaned and imported; where history is too messy to structure, it is archived and linked so it remains accessible.
The first module — usually master data and inventory — is typically live within 8–12 weeks. Further sheets are migrated in phases so the business keeps running.
Yes. Analysis and what-if sheets often stay; they can read live data from the ERP instead of copies. Sheets that act as the record of stock, sales or dues are the ones we replace.
That is normal. We run validation reports, fix issues with your team, and repeat the trial import until it is clean. Dirty data is a reason to migrate carefully, not a reason to stay in Excel.
No. Screens are designed for the people who used the sheets, in Bengali, English or German, and training happens on their real data.
