How to Align Contract Payments, Imports and Subcontracting Before a Project Starts

Your main contract is signed and equipment is ready to ship, but finance still does not know who should import the goods, who should be paid, or whether a subcontractor should invoice separately. This is the point at which project tax and cost-allocation issues are most often created.

Do not wait until the first payment, first import declaration or first subcontractor invoice to reconstruct the paperwork. Mapping the transaction flow before work begins is usually less costly than explaining it afterwards.

A common assumption is that a clearly drafted EPC or main contract is enough. In practice, it may define the project scope without answering whether equipment is being sold, leased or supplied as project material; how offshore services and local construction work are separated; whether the importer and end user are the same party; or who accepts subcontracted work and when payment becomes due. These gaps commonly lead to repeated requests for payment documents, difficulty matching customs records to contract values, and project costs that cannot be allocated accurately between contract packages, equipment and construction services.

Build a map of funds, goods and services

Before mobilisation, do not leave legal, procurement and finance teams holding separate versions of the project records. Put the main contract, purchase orders, payment plan, import arrangements and subcontract scope into one working file.

The file does not need to be sophisticated at the outset. It should allow the project lead, finance team and appointed professional advisers to understand the same basic picture: where money is paid from, where goods enter, and who performs the services.

For each contract package, record at least the following:

Review item	Questions to clarify
Contracting parties	Who signs the contract, pays, receives payment, uses the goods or services, and accepts delivery or completion? Are offshore related parties involved?
Deliverables	Are they equipment, materials, design, installation, commissioning, site works, management support, or a combination?
Place of delivery	Where are goods delivered? Where are services actually performed? Does the project involve more than one site?
Pricing method	Is the price a lump sum, milestone-based amount, quantity-based charge, provisional sum, reimbursable cost plus fee, or a mixed arrangement?
Payment terms	What supporting documents are required for advance payments, shipment payments, delivery payments, acceptance payments and retention amounts?
Invoices and evidence	Who is expected to issue which documents? Can the amount, currency, contract reference and payment stage be reconciled across them?
Import responsibility	Who is responsible for import-related declarations and customs clearance arrangements? Who bears freight, insurance, port and clearance costs?
Subcontracting	What work does each subcontractor perform? Is further subcontracting expected? Who purchases and supplies materials to site?

The purpose of this table is not to replace tax analysis. It is to assemble the facts needed for that analysis in one place. Without a complete factual record, even an external adviser who has received the contracts may struggle to identify the tax, customs or payment-compliance issues that require attention.

Do not rely only on the internal budget when separating contract elements

Construction projects often combine equipment supply and installation, design-procurement-construction services, offshore supply with local commissioning, or a main contractor coordinating several local subcontractors. Your internal budget may group all of these under “project cost”. External contracts, invoices, import records and payment documentation should not necessarily follow that single label.

Ask your appointed tax and legal advisers whether different deliverables under the contract need to be identified separately; whether supporting documents should be retained for equipment, materials, installation, design, training and site management; and how contract variations, additional works or claims should be documented. A lump-sum contract price does not necessarily mean that every later document can use one broad description.

For example, procurement may already have obtained an equipment quotation while the project team separately arranges for installation personnel to enter the site. If the equipment contract, shipping documents, installation agreement and payment request do not share a common reference or cross-reference each other, it can become difficult to explain whether a payment relates to goods, services or both. The larger the project value, the more important document traceability becomes.

Check at least four points before making a payment

1. Confirm that the payee matches the contractual recipient. If it does not, understand the commercial reason for the arrangement and retain relevant authorisations, assignments or payment instructions.
2. Trace the payment amount back to a contract milestone. Advance payments, progress payments, reimbursements, retention amounts and variation payments should not be combined under one unclear payment description.
3. Ensure the payment purpose matches the supporting documents. The contract, invoice, payment request, acceptance evidence, shipping documents and bank payment narrative should use project names and references that can be matched.
4. Identify required tax treatment before payment is made. For payments involving offshore suppliers, cross-border services, related parties, subcontracting or payments made on behalf of another party, confirm the required treatment, record-keeping and filing arrangements with appointed professional advisers before issuing the payment instruction.

Payment is not merely an accounting action. It fixes the contractual position, bank support documents, tax records and project-cost treatment at the same time. Recharacterising an amount that has already been paid as a different type of transaction later will usually increase communication and correction costs.

Align import documents with the project contract before equipment arrives

Before equipment, construction machinery, spare parts or project materials enter Sri Lanka, the project team should establish who prepares commercial documents, who coordinates customs clearance, who pays the relevant costs, and how import records will ultimately feed into the project cost ledger. The import contract does not need to be identical to the main contract, but their relationship should be explainable.

Create an import-shipment register. Each shipment should be linked at least to the supplier, purchase order or contract reference, goods description, quantity, transport documents, expected arrival arrangements, customs-clearance responsibilities, related project package, payment status, and warehouse receipt or site acceptance record.

If equipment is purchased by an offshore related party and then made available to the local project entity, explain the full transaction chain to professional advisers before shipment. Do not submit only the final layer of documentation.

Another common misunderstanding is that, once a customs broker can complete the declaration, the project company no longer needs to pay attention to import records. In reality, the customs arrangement resolves the operational issue for a particular shipment. The project company still needs to ensure that contracts, commercial documents, payment records and internal asset or materials registers can be reconciled.

This matters especially where equipment goes directly from the port to site, is issued to a subcontractor, or is delivered together with installation services. Internal receipt and issue records should not be omitted.

For a practical approach to checking import declarations, tax payments and cargo-release status, refer to the published guide, After Appointing a Customs Broker for Imports: How to Check Declarations, Taxes and Cargo Release Status. If contract values, import declaration values and payment amounts do not match, procurement, finance, project personnel and customs coordination parties should investigate the issue together as early as possible after payment or declaration. It should not be left to one department to revise an explanation on its own.

Subcontracting is more than simply hiring people to work on site

Subcontracting arrangements are often finalised gradually after a project starts. That is why they can easily become disconnected from the tax and cost logic of the main contract. Start by defining whether the subcontractor is providing labour, installation, specialist construction work, equipment supply, site management, or integrated work that includes materials and machinery.

Different arrangements require different contract wording, acceptance records, payment applications and site documentation.

Each subcontract should at least be linked to a main-contract project package and should clarify:

• the work scope, site location and expected deliverables;
• who provides materials, equipment, tools, accommodation, transport or safety-management support;
• who signs progress confirmations, quality acceptance documents and payment applications;
• how variations, work stoppages, rework, material losses and retention amounts are recorded;
• whether the subcontractor may use other construction parties, and which supporting documents the project needs to obtain; and
• whether the subcontractor's invoicing details, payment account details and contracting-entity information are consistent.

Do not classify every site expense as “construction cost”. If site purchases, temporary labour, equipment hire, transport and specialist subcontracting are all recorded under the same cost code, it can be difficult at project close-out to identify which contract, work item and payment each cost relates to. For projects that must settle with an owner, report to investors or support an audit, this directly affects the efficiency of document preparation.

Quotations and budgets: separate the uncertainties

At the project-start stage, management will usually want to know how much tax and related professional support may add to project costs. Do not ask advisers only for a single total fee. A more useful quotation should state the scope of work, the number of contracts and transaction complexity on which it is based, the types of documents to be reviewed, deliverables, whether subsequent changes are charged separately, and what work is excluded.

Fees can vary with the number of contracts, frequency of offshore payments, number of import shipments, subcontracting layers, completeness of records, contract changes, and whether historical documents must be reconstructed within a short period. You can divide the budget into three parts: contract and transaction-flow review before project start, payment and import support during execution, and filing or ongoing compliance support after operations begin.

This is easier to compare than placing every professional cost into one “consultancy fee” line. It also helps the project lead decide when additional support is needed.

A minimum coordination process before mobilisation

Before the first payment and the first equipment shipment, hold one document-review meeting involving the project, procurement, finance, contract-management teams and appointed professional advisers. The meeting does not need to debate abstract rules. It should confirm, item by item, whether the main and subcontract agreements are complete; whether the payment plan aligns with delivery milestones; whether import responsibility is clear; how the project cost ledger will be coded; which payments need further confirmation before execution; and who will retain original documents and update variation records.
