A time-and-materials contract (TMC) is an agreement typically used in software development projects which pays contractors according to the time and materials required for project completion. The agreement sets an hourly labour rate while clients reimburse contractors for materials costs incurred during completion. CTCs are frequently utilised when the scope of a project remains ambiguous while clients need flexibility during its development process.

Businesses widely utilise contract models to establish the terms and conditions of agreements between two or more parties. Contract models help ensure both sides understand their roles and responsibilities and any scope, timelines, or compensation arrangements agreed to in advance. Contract models also serve to facilitate successful collaboration by minimising disputes or miscommunication.

The Benefits of Time and Materials Contract

There are multiple reasons for their importance:


Contract models provide clarity about each party’s expectations. By outlining the scope, timeline, and compensation agreements in detail, both parties can ensure that they can understand exactly what is expected from contract models.


Contract models provide both parties with protection by outlining the terms and conditions of an agreement, acting as a legal framework to address disputes or minimise misunderstandings.


Contract models hold both parties responsible for meeting their responsibilities. By clearly outlining expected deliverables and timelines, contract models ensure both parties understand what is expected from them and can be held to account if they fail to fulfil them.


Contract models can be tailored to the unique requirements of any given project, meeting its scope, timeline and complexity with fair and reasonable agreements. Various contract models may be utilised depending on what works best.


Contract models facilitate the establishment of agreements more quickly. By providing an easily adaptable template that can be personalised to the needs of each project, contract models save parties both time and effort in negotiating terms and conditions for agreements.

The Benefits of a Time and Materials Contract


Time-and-materials contracts provide flexibility to both the client and contractor. Clients can adjust project scope and budget, and monitor progress, while contractors can tailor development to client requirements.


Time-and-materials contracts provide clients with greater transparency. They can see exactly where time and money are spent on a project in real time, allowing for improved decision-making and cost control.


Because contractors are paid hourly, they are incentivised to deliver high-quality work to avoid delays and rework.

Cost Control

Time-and-materials contracts allow clients to pay only for what is used rather than an all-inclusive fixed price for the project, potentially saving costs if the scope is reduced.

Time and materials: How to do it correctly

Define the Project Scope

For any time-and-materials contract to succeed, its scope must be established. Both client and contractor should agree on deliverables, timelines, milestones etc.

Establish a Realistic Budget

Clients should establish an accurate budget for the project and be open to making adjustments as necessary. Contractors should provide detailed estimates and transparent pricing details.

Establish Communication Protocols

Effective communication is vital to the success of time-and-materials contracts. Both client and contractor should create communication protocols, such as regular check-ins and progress reports, to facilitate successful project outcomes.

Monitor Progress

To ensure their project remains on schedule, clients should regularly assess progress through regular progress reports or check-ins with project staff. Doing this allows any issues or missteps to be identified early so course correction can occur as necessary.

How Time and Materials Contracts Work

Time and materials contracts pay contractors according to the time and materials consumed for completing a project. They provide flexibility, transparency, quality, and cost control features which often make this type of agreement popular among software development projects with uncertain or variable scopes. This contract offers these benefits while meeting client expectations on payment for labour costs and materials reimbursement.


When selecting a time and materials contract provider for your software development project, selecting an experienced software development company with proven results in high-quality work delivery, meeting deadlines on schedule, effective client communication and understanding of client needs will help ensure its successful outcome.

3. How can clients ensure contractors are not overcharging for materials?

Clients can ensure contractors do not overcharge by obtaining detailed receipts and invoices for purchases and comparing those costs against market prices.

4. What are the advantages of time-and-materials contracts for software development projects?

Time-and-materials contracts offer clients great flexibility, transparency, quality and cost-control benefits. Clients can change the scope and budget while tracking project progress; contractors are incentivised to produce high-quality work as their hourly pay increases accordingly.
