Your model audit shouldn’t be a bottleneck for progress. 

Gridlines’ unique top-tier industry practices combine meticulous attention to detail with a streamlined process that eliminates the traditional pains of auditing. No more frustrating delays, no more endless back-and-forth.

Why miss out on smoother, smarter, stress-free audit

Why choose to endure weeks of delay...

Suffering weeks of delay before receiving your first feedback is not only nerve-wracking, it also means critical time is lost, limiting your ability to tackle major issues and stifling vital project momentum.

...When you can have this

We deliver first feedback in just 3-4 DAYS, enabling quicker problem-solving, enhanced decision-making, and significantly reduced stress. 

Why choose unpredictable iteration charges...

Iteration charges are the industry standard. That means worrying about costs escalating outside of your control is standard too. 

...When you can have this

At Gridlines, we believe there’s a better way. Regain control of your budget with our fixed-fee model audit. 
No surprises. No embarrassing over-spends. 

Why endure the back and forth of old fashioned issue lists...

Traditionally model auditors share long lists of issues in several rounds. This is inefficient and adds delay and unpredictability into the process. 

...When you can have this

We use the latest online collaboration tools and our unique “live shared issues list” to ensure you’re notified immediately when we find something in the model. 
No more bouncing issues back and forth on issues logs for weeks on end. Just swift collaboration and faster resolutions.

Game changer

“Gridlines have been a great addition to the model-audit landscape, bringing fresh thinking and technology, a user-friendly commercial approach and an impressively experienced team”.
