VAT/AIT Costing
Bid Cost Calculator
Know your margin before you submit — BOQ, VAT/AIT, and profit clarity.
Bid Cost Calculator on GoBiDx
GoBiDx is procurement intelligence for Bangladesh — tender discovery, AI bid preparation, supplier marketplace, and corporate RFQ in one workspace. Teams that coordinate bidding, costing, and compliance in a single system respond faster to addenda and submit more complete files than competitors juggling spreadsheets and email threads.
Why VAT/AIT Costing teams use this capability
Whether you pursue e-GP packages, NGO frameworks, or LGED infrastructure works, the feature Bid Cost Calculator addresses a recurring bottleneck: turning tender requirements into actionable workflows before deadlines close.
What you gain
- Line-item BOQ cost estimation
- Margin visibility before bid submission
- VAT / AIT / TDS impact aligned to BD practice
- AI cost analysis via Tender Intelligence
- Fewer post-win losses from bad costing
Practical workflow
Start from the live tender or RFQ record, attach BOQ and compliance notes, assign internal reviewers, and export submission-ready documents. Track VAT/AIT assumptions alongside technical method statements so financial and technical leads work from the same baseline numbers.
VAT and AIT basics for tender pricing
Mis-stated VAT or AIT treatment is a frequent cause of bid rejection or post-award disputes. Know whether quoted rates are inclusive or exclusive of VAT, which services attract supplementary duty, and how AIT applies to contractor payments. Align BOQ notes with your tax advisor’s written opinion for high-value bids.
Keep TIN and VAT registration active and consistent with trade licence names on all bid forms.
Building a compliant cost build-up
Separate direct costs, indirect costs, profit, and taxes in internal worksheets even when the tender requests a single line price. Trace every BOQ item to a supplier quote or productivity norm. Contingency should be explicit internally even if not disclosed externally.
GoBiDx costing tools help teams structure VAT/AIT lines and export reviewer-friendly summaries for internal approval.
Avoiding tax-related disqualification
Submit current tax clearance certificates where required. If a tender allows provisional clearance with undertaking, follow the exact wording — generic letters fail compliance. After award, ensure invoicing matches bid tax treatment to avoid payment delays.
