Marine ERP Software: Ship Chandlers, Shipyards & Marine Services (2026)
Short answer: Marine businesses — ship chandlers, marine service and engineering companies, shipyards, shipping agencies and seafood exporters — are poorly served by generic ERP because their work is organised around a vessel and a port call, not a customer and an order. The systems that work let you quote, supply, and invoice against a specific vessel on a specific call, handle bonded and duty-free stock, and cost each job or docking separately. ERPNext is usually the strongest fit in the Gulf and India: it is open-source, so vessel-call and job-costing structures can be modelled properly rather than forced into a sales-order template, and it has no per-user licence fees.
Compliance in one line: UAE 5% VAT with e-invoicing compulsory for larger businesses from 1 January 2027; Qatar has no VAT and only a draft e-invoicing law; Kuwait has no VAT (a 15% DMTT applies to large multinationals); India requires IRN and QR on invoices once turnover has passed ₹5 crore.
Search for “marine ERP software” and you will find very little written for this sector — not because the sector is small, but because marine operators rarely search that phrase. They search for the problem in front of them: how to bill a disbursement account, how to track spares against a vessel, how to keep bonded stock straight. This guide is written for those problems.
Why generic ERP struggles with marine work
Most ERP systems assume a stable customer who places orders that ship to an address. Marine work breaks all three assumptions. The paying customer is often an owner or manager in another country, the delivery point is a vessel that will be alongside for a matter of hours, and the same vessel may be served under different principals on different calls.
The practical consequence is that the vessel call — not the sales order — is the unit that everything should hang from: the enquiry, the quotation, the supply, the costs, and the invoice. Systems that cannot represent that end up tracked in spreadsheets alongside the ERP, which is where margin quietly disappears.
What each type of marine business actually needs
Ship chandlers and marine supply
- Quote against a vessel and a call, with the agent or owner as the payer — then convert quotation to supply to invoice without re-keying.
- Bonded and duty-free stock kept separate from duty-paid stock, because the tax treatment differs and mixing them is an audit problem.
- Delivery windows measured in hours. Stock availability has to be truthful at the moment of quoting, not at end of day.
- Multi-currency with clean realised and unrealised FX — quoting in USD while buying in AED or INR is the norm.
- Provisions, stores, spares and safety items with very different margins — so margin must be visible per line, not per invoice.
Marine services, engineering and repair
- Job cards per vessel capturing technician hours, spares consumed and subcontracted work.
- Costs committed before the supplier invoice arrives — otherwise a job looks profitable until the paperwork catches up.
- Warranty and rework tracked against the original job rather than written off as a new cost.
- Certification and calibration records attached to the equipment, since clients audit them.
Shipyards and dry dock
- Each docking is a project, with its own budget, progress billing and retention.
- Variation orders agreed mid-docking must reach the invoice — unbilled variations are the single most common leak in this business.
- Yard capacity and berth scheduling visible alongside the commercial position.
Shipping agencies
- Disbursement accounts. Proforma DA, funds received from the principal, actual port charges paid on their behalf, then a final DA that reconciles. This is agency-specific accounting and generic ERP has no concept of it.
- Clear separation of your revenue from money held and spent on a principal’s behalf — blurring the two overstates turnover and confuses tax.
Seafood and marine product exporters
- Lot and batch traceability with grade-based pricing — two consignments of the same species are not the same item.
- Cold-chain records, export documentation and duty drawback handled inside the same ledger. Relevant across Kerala’s seafood export base.
Compliance by country
United Arab Emirates
5% VAT with FTA-compliant tax invoices, and 9% corporate tax on profits above AED 375,000. The bigger change is the Electronic Invoicing System: voluntary from 1 July 2026 and mandatory for businesses with revenue of AED 50 million or more from 1 January 2027, with smaller businesses following on 1 July 2027. For marine businesses this matters more than most, because free-zone and mainland entities are common and each transfer between them carries a VAT treatment that a structured e-invoice will expose.
Qatar
Qatar does not have VAT — no rate, no threshold, no announced date. In May 2026 the Council of Ministers approved a draft electronic invoicing law, which still requires further passage before it takes effect. Corporate income tax on foreign-owned profits is filed through Dhareeba, and salaries run through the Wage Protection System. The sensible posture is readiness, not urgency.
Kuwait
Kuwait has not introduced VAT either, and current policy favours other instruments over it. A Domestic Minimum Top-up Tax of 15% took effect on 1 January 2025, but it applies to large multinational groups (consolidated revenue of EUR 750 million or more) — most Kuwaiti marine businesses are outside its scope. No e-invoicing mandate has been announced. In practice this means Kuwait operators should optimise for operational control now, and choose a system that can absorb VAT later without being replaced.
India
GST e-invoicing is mandatory once aggregate annual turnover has exceeded ₹5 crore in any financial year since 2017–18, and the obligation is permanent once crossed. An invoice without a valid IRN and QR code is invalid, so your customer cannot claim Input Tax Credit against it — a back-office slip becomes a commercial problem. Goods movement needs e-way bills, which should be produced from the same document as the invoice rather than re-keyed.
Why ERPNext suits marine operators
Marine work needs structures that off-the-shelf systems do not ship with: a vessel-call record, a disbursement account, a docking project. Because ERPNext is open-source, those can be modelled as first-class objects rather than bent into a sales-order template — and adapted again as the UAE and Qatar e-invoicing rules land. There are no per-user licence fees, which matters in a sector that scales headcount with vessel traffic. The honest trade-off: ERPNext rewards a competent implementation and punishes a careless one.
We build our own software on ERPNext rather than only configuring it — our Sellbee route-sales application is one example, and a Gulf distributor running it grew from 7 vans to 15. That engineering capability is what makes vessel-call and DA structures practical rather than theoretical.

Frequently asked questions
What is marine ERP software?
Marine ERP software is an enterprise system configured around how marine businesses actually operate: work is organised by vessel and port call rather than by customer and sales order. It typically adds vessel-call records, job cards per vessel, bonded and duty-free stock separation, disbursement accounting for shipping agencies, and project costing per docking, on top of standard accounting, inventory and payroll.
Which ERP is best for a ship chandler?
For most ship chandlers in the Gulf and India, ERPNext is the strongest fit. It can quote against a specific vessel and call with the agent or owner as payer, keep bonded stock separate from duty-paid stock, handle multi-currency quoting and buying, and show margin per line rather than per invoice. Being open-source, the vessel-call structure can be modelled properly, and there are no per-user licence fees.
How does ERP handle disbursement accounts for shipping agencies?
A disbursement account tracks money spent on a principal's behalf during a port call: a proforma DA is issued, funds are received, port charges and services are paid out, and a final DA reconciles the difference. Generic ERP has no concept of this, so it must be modelled explicitly - keeping agency revenue separate from principal funds, which otherwise overstates turnover and confuses tax reporting.
Do marine businesses in Qatar and Kuwait need to worry about VAT?
Neither country has VAT today. Qatar has not introduced it and has published no rate, threshold or date, though a draft e-invoicing law was approved in May 2026. Kuwait has also not introduced VAT; its 15% Domestic Minimum Top-up Tax, effective January 2025, applies only to large multinational groups with EUR 750 million or more in consolidated revenue. The practical advice for both is to choose a system that can absorb VAT later rather than needing replacement.
What changes for marine businesses in the UAE in 2027?
The UAE Electronic Invoicing System becomes mandatory for businesses with revenue of AED 50 million or more from 1 January 2027, with smaller businesses following on 1 July 2027. Invoices must be exchanged as structured data rather than PDFs. Marine businesses often run both free-zone and mainland entities, and structured e-invoicing will expose any inconsistency in how transfers between them are treated for VAT.
Can ERPNext handle seafood and marine export traceability?
Yes. ERPNext supports lot and batch tracking with grade-based pricing, which is what seafood and marine product exporters need since two consignments of the same species are not interchangeable. Cold-chain records, export documentation and duty drawback can be handled in the same ledger, and Indian exporters get GST e-invoicing with IRN and QR alongside it.
