Should You Build or Buy Quoting Software

Every digital manufacturer reaches a point where spreadsheets and manual calculations can’t keep up. RFQs pile up, lead times stretch, and margins erode. The question isn’t whether you need better quoting — it’s how to get there.

You have two paths: build a custom solution in-house, or buy a platform purpose-built for digital manufacturing. Both can work. But the hidden costs, timelines, and opportunity costs differ wildly.

What Building Actually Costs

Custom software feels like control. Your team knows your pricing logic, your material library, your edge cases. But control comes with a price tag most shops underestimate.

• Engineering time: A minimum viable quoting engine takes 6–12 months of dedicated dev work. That’s senior engineers pulled from core product or automation projects.
• Domain complexity: Quoting isn’t CRUD. It’s nesting algorithms, multi-process cost accumulation, material yield calculations, post-processing rules, and customer-specific pricing tiers — all interacting.
• Maintenance burden: Every new machine, material, or process change means code changes. API updates from ERP or CAD partners break things. You own the bug queue forever.
• Integration debt: Connecting to your ERP, CRM, and shop floor systems is its own project. Custom integrations rot faster than vendor-maintained ones.

One CNC shop we talked to spent 14 months building a quoting tool. By launch, their pricing logic had already changed twice. They’re now on version three and still haven’t recovered the dev investment.

What Buying Gives You (And What It Doesn’t)

A platform like Solvi delivers a quoting engine configured to your processes — not a generic calculator. The difference matters.

• Time to value: Weeks, not months. You configure pricing rules, material libraries, and workflows through a UI your estimators can own.
• Manufacturing-native logic: Nesting-aware pricing, multi-process accumulation, build-plate optimization for additive, sheet metal yield calculations — built in, not bolted on.
• MES and job board included: Quoting doesn’t exist in a vacuum. Solvi connects quotes to production workflows and a capacity marketplace so overflow work fills idle machines.
• Vendor-maintained integrations: ERP, CRM, CAD, and accounting connections update automatically when partners change APIs.

What you give up: total code-level control. If your pricing model is genuinely unprecedented — not just complex, but structurally unique — a platform may need customization hooks. Most shops overestimate how unique their logic actually is.

The Decision Framework

Ask these five questions. Be honest.

1. Is quoting a competitive differentiator or a cost center? If your quoting process is your secret sauce, build. If speed, accuracy, and capacity utilization are the levers, buy.
2. Do you have 2+ senior engineers free for 6+ months? Not “can we hire” — do you have them now, and can you afford the opportunity cost?
3. How often does your pricing logic change? Quarterly material updates, new machines, revised post-processing rules? Each change is a sprint in a custom build.
4. What’s the cost of a quoting error? One bad nest on a $50K build plate or a missed rush-order premium pays for years of a platform subscription.
5. Can your estimators own the tool? A platform lets non-technical users adjust rules. Custom code requires a ticket queue.

If you answered “buy” to three or more, the math favors a platform.

Hybrid Approach: Buy the Core, Extend the Edges

Some shops do both well. They buy a quoting engine with an open API, then build custom workflows around it — customer portals, automated DFM checks, specialized reporting.

Solvi’s API lets you push quote data into your ERP, pull customer pricing tiers from your CRM, or trigger production workflows in your MES. You own the edges; we own the quoting math, nesting logic, and manufacturing integrations.

This hybrid model is often the sweet spot: fast launch, low maintenance, full extensibility where it actually matters.

What Shops Regret Most

We’ve talked to dozens of shops who built first. The pattern is consistent:

• Underestimating nesting and multi-process complexity by 3–5x
• Losing the engineer who built it (knowledge walks out the door)
• Quoting improvements stalling because every change is a dev project
• Realizing too late that MES integration was the harder problem

The shops that bought? They regret not doing it sooner. The ones that went hybrid? They wish they’d started with the platform instead of wasting a year building the core.

Next Steps

Map your current quoting workflow end-to-end. Time each step. Count the manual handoffs. Identify where errors happen and what they cost.

Then run the numbers: dev hours × loaded cost vs. platform subscription × 3 years. Factor in opportunity cost — what else could those engineers ship?

If the gap is significant, Solvi can show you a configured demo with your actual pricing logic, materials, and processes — so you see exactly how it fits before you decide.
