DesignSilc is a global accounting and legal software development company with teams in Dhaka, Austin and the UK, serving clients in 38+ countries. We build accounting software, tax-ready invoicing and return support tools, law firm case management systems and audit firm software for businesses and professional practices. Our systems keep purchase and sales registers, produce compliant tax invoices and organise the data your team needs to prepare returns, from NBR VAT (Mushak) in Bangladesh to sales tax in the USA and VAT/MTD in the UK. Our 70+ developers have delivered 1,000+ projects since 2015.
For legal and advisory firms, we build case and matter management with hearing dates, court details, document storage, time tracking and client billing. Audit and tax practices get client files, working papers, review sign-offs and deadline calendars. VAT and tax rules change, so we build rates and form layouts as configurable settings and work with your accountants or advisers to confirm each output. Every accounting system now includes AI that supports your finance team: it matches bank lines, reads supplier bills and pre-checks VAT returns, while your accountants review and sign off every figure.
Systems that keep your books, tax records and case files accurate, organised and ready for review.
Chart of accounts, vouchers, bank reconciliation, party ledgers, trial balance, profit and loss and balance sheet by branch.
Generate tax invoices with registration numbers, rates and serials from sales or POS, in local formats such as UK VAT or Mushak-6.3.
Purchase and sales registers, input-output tax summaries and exports to help prepare periodic returns and withholding records.
Matters, clients, court and hearing dates, cause lists, tasks, document vault, time entries and SMS hearing reminders.
Client engagement files, working papers, checklists, reviewer sign-off, deadline calendars and fee billing.
Secure portal where clients upload documents, view case or filing status, approve work and pay invoices online.
AI does the matching, reading and checking that fills month-end, then explains each exception in plain words. Your accountants and advisers stay in charge of entries, returns and filings.
Ask for any ledger, ageing or tax report in plain words and get the table, chart and filters it used.

Learn more →Yes. DesignSilc builds accounting and sales software that generates tax invoices in local formats, such as UK VAT invoices, US sales-tax invoices or the Mushak-6.3 format, including registration numbers, rates and sequential serials. Rates and layouts are configurable so they can be updated as rules change, and we review outputs with your tax adviser before go-live.
Cost depends on the modules needed, such as accounting, inventory, tax invoicing, return support or POS integration, plus users and branches. DesignSilc gives clients in the USA, UK, Europe, Middle East and South Asia a fixed quote after a free discovery call. Many businesses start with an MVP for invoicing and core accounts, then add tax registers, inventory and reporting in phases.
A first release with chart of accounts, vouchers, tax invoicing and core financial reports typically takes 8 to 14 weeks. Law firm case management systems typically take 6 to 12 weeks. DesignSilc migrates opening balances or case records so your team can start with complete data.
DesignSilc software organises sales, purchases and tax into registers and summaries that support preparing your periodic returns, and can export them in the formats your team or filing channel uses, including integrations such as HMRC MTD where an official API exists. Final filing stays with you or your tax adviser. We build to support the process, not replace professional review.
Yes. DesignSilc builds case management software for law firms and legal departments, covering matters, clients, courts, hearing dates, next steps, documents, time tracking and billing. Lawyers get daily cause lists and SMS or app reminders, and partners can see workload and outstanding fees across the firm.
Our accounting systems include a finance copilot for plain-language reports, bank and mobile wallet auto-matching, supplier bill OCR, withholding and VAT calculation on each payment, VAT return pre-checks, register validation, duplicate and anomaly detection, collection priority scoring, cash flow forecasting and budget variance explanations. For legal and audit practices, AI can summarise matter files and working papers for review. These tools support your accountants and advisers rather than replace them: AI prepares and flags, and qualified people review, sign off and file each return.
Yes. The system ships with an MCP server, so Claude, ChatGPT, Cursor or agents your firm builds can read ledger balances, receivables ageing, unmatched bank lines and VAT return summaries through defined tools. Access follows each user's role, so an assistant working for a junior clerk sees what that clerk sees and nothing more. Vouchers, bank matches, reminders and return drafts are proposals until an accountant approves them, and each tool call is kept in an audit log. You can choose the AI model, including a private, on-premise model for client confidentiality.
