The cost of custom accounting software is driven by seven things: the modules you need, the complexity of users and permissions, the number of branches, integrations with systems such as your website or POS, migrating existing data, tax and custom reports, and training. EOMS BD prices these in a written, line-by-line quote once requirements are clear, showing first-year costs separately from every year after.
- Biggest drivers: the number of modules and the integrations.
- Simplest saving: launch with the essential modules and add the rest in phases.
- Zero licence cost: the system is custom, so there are no theme or plugin licences to buy.
- After year one: hosting and domain renewals are paid directly to the provider, not to EOMS BD.
- Payments: three milestone instalments, each after you check the work on a demo link.
What drives the cost: an overview
Cost follows the amount of work: how many modules, how complex the rules, which systems it must connect to, and how much data and training is involved. Any fixed price quoted before someone has heard your requirements is usually incomplete.
Consider two businesses. A single shop wants sales, expenses and a month-end profit and loss, used by one person. A distributor has three warehouses, ten users, approval steps, orders arriving from its website and several years of data in an old system. Both want "accounting software", but the scope, and therefore the cost, is completely different.
| Driver | Why it affects cost | How to control it |
|---|---|---|
| Modules | Each module needs its own screens, rules and reports | Launch with essentials; add the rest later |
| Users and permissions | More roles, approval steps and audit logging mean more logic and testing | Start with a simple role structure |
| Branches | Branch-level books and consolidated reporting are extra work | Start with head office; add branches in a later phase |
| Integrations | Exchanging data with a website, POS or other software | Prioritise the integration that saves the most daily effort |
| Data migration | Cleaning, reconciling and importing old data takes time | Tidy your data in spreadsheets beforehand |
| Tax and custom reports | Each specific report format is built individually | Agree a list of must-have reports early |
| Training | More staff and branches mean more sessions | Train one lead user per department who supports the rest |
For what a custom system includes and how the project runs, start with custom accounting software development.
Modules and scope
The module list sets most of the budget. A system with vouchers, ledgers and financial statements is a very different scope from one that also covers sales, purchasing, inventory and payroll.
The accounting core typically includes the chart of accounts, vouchers (journal, payment, receipt and contra), ledgers, cash and bank books, trial balance, profit and loss and balance sheet. On top of that you might add:
- Sales and purchases with invoices, plus customer and supplier dues
- Inventory with stock valuation
- Expense tracking and payroll
- Bank reconciliation
- English and Bangla interfaces, Excel and PDF export
The rules inside each module matter too. Which stock valuation method you use, whether one product is sold in several units (piece, box, carton), or whether invoices can be collected in instalments all change the work involved. The clearer these decisions are up front, the more accurate the quote.
Users, permissions and branches
More roles, approval steps and branches mean more logic and more testing, so they increase the scope.
Software used by an owner and one accountant is far simpler than software used across five branches, where cashiers, branch managers, an accounts manager and an auditor each need different access. The second case needs:
- Role-based permissions controlling menus, branches and reports for each user.
- Approval workflows: entry, review, approval, then posting.
- An audit log recording who changed which entry and when.
- Branch-level books with consolidated reporting across all branches.
- Inter-branch transfers of cash or stock.
If you have one location today but plan to open more, say so at the start. The database can then be designed for branches from day one, which makes adding them later simpler and cheaper.
Integrations with your website, POS and other systems
Integrations remove manual data entry, but each one is a separate piece of work and appears as its own line in the quote.
The most common request is connecting a website or POS so that online orders and shop sales post automatically to invoices, stock and the ledger. The effort depends on:
- Whether EOMS BD built the other system; connecting our own systems is usually simpler.
- Whether the other system has an API, or data must move by file export and import.
- Whether data flows one way or both ways.
- How many special cases must be handled, such as returns, cash-on-delivery settlements and courier charges.
The full order-to-ledger flow is explained in e-commerce and accounting software integration. If you need a new website as well, planning both together usually reduces the total work.
Data migration, tax reports and training
These three items are often missing from early quotes and later appear as unexpected costs, so discuss them as separate lines from the start.
Data migration
Opening balances, customers and suppliers with their dues, and products with stock all need to be brought across. Clean spreadsheets mean less work; data scattered across ledgers, an old system and separate files takes longer to reconcile.
Tax and custom reports
VAT-related reports can be built, but each specific report format is separate work. Agree the formats and rules with your accountant before development starts.
Tax rules differ by country and change over time. Confirm current requirements and report formats with your tax authority (for example, the National Board of Revenue in Bangladesh) or your accountant. If rules change later, report updates are scoped and priced as new work before they start.
Training
The amount of training depends on the number of staff, branches and modules. Training one responsible person per department in depth, who then supports colleagues, keeps this manageable.
Year-one costs versus every year after
Development is a one-off cost. In later years the main costs are hosting and domain renewals, which you pay directly to the provider; they are not an EOMS BD charge.
| Cost item | When | Paid to |
|---|---|---|
| Software development | Once, in three milestone instalments | EOMS BD |
| Hosting and domain | Renewed yearly | The provider, on your own account |
| Theme or plugin licences | Not applicable: zero cost | None |
| Yearly maintenance | Optional, only if EOMS BD maintains the server | EOMS BD |
| New features | When you need them | Priced and agreed before work starts |
Every project includes 6 months of free support and 1 year of free bug fixing after launch, where a bug means a problem in an existing feature. SSL is free for the lifetime of the system, and backups run daily.
How to keep the cost down, and what the written quote includes
Clear requirements, a phased launch and tidy data are the most reliable ways to keep a custom accounting project within budget.
- Check whether ready-made is enough: if your rules are standard, EOMS BD's cloud accounting software may already fit, and you may not need custom development at all.
- Separate essential from later: put only what you cannot operate without into phase one.
- Share sample reports: copies of the reports you use today prevent work on features nobody needs.
- Prepare your data: clean opening balances and master lists in spreadsheets before migration.
- Share future plans: mentioning upcoming branches or integrations lets the structure accommodate them, avoiding costly rework.
How to compare quotes
Comparing only the total can mislead, because one quote may include work another leaves out. Ask:
- Is every module and report listed as a separate line?
- Are data migration and training included, or charged later?
- Will you receive the source code and database, or only a licence to use the software?
- What are the costs in later years, and who are they paid to?
- How long are support and bug fixing, and how is a "bug" defined?
Our written quote lists each module and task line by line and shows first-year costs separately from later years. Payment is in three milestone instalments: an advance, after the design is approved, and after the admin panel and modules are complete, each released after you review the work on a demo link. The quote also states that the source code, database and hosting are yours; see accounting software with full source code and data ownership.

Frequently asked questions
How much does custom accounting software cost?
There is no single price, because cost depends on modules, users and branches, integrations, data migration, tax reports and training. Once we understand your requirements, we send a written, line-by-line quote.
Which factor increases the cost the most?
Usually the number of modules and the integrations with other systems. Multi-step approvals, several branches and custom report formats also add significant work.
Can we start with a small budget?
Yes, by phasing the project. Start with the essential modules such as vouchers, ledgers and core financial statements, then add inventory, payroll or branches later. Sharing future plans at the start makes later additions simpler.
Are there ongoing yearly fees for the software?
Development is a one-off cost. In later years you renew hosting and domain directly with the provider, which is not an EOMS BD charge. Yearly maintenance is optional and applies only if EOMS BD maintains the server.
How are new features priced after launch?
New features are priced by scope and agreed in writing before work starts. Bugs in existing features are fixed free for 1 year after launch.
What does the written quote include?
Each module and task as a separate line, first-year and later-year costs shown separately, the three-instalment payment structure, and the terms confirming the source code, database and hosting are yours.
