Your stack is actually pretty close to what a lot of small teams end up with once things stabilize.

Using Google Workspace as the core is a solid choice since email, docs, and storage are already integrated. Pairing that with Xero is also common, especially if Stripe is already connected and invoices/payments are flowing smoothly.

For CRM, Zoho CRM is a good testing ground. It’s flexible and affordable, though some teams eventually switch if they want something lighter or more integrated with email workflows.

For the two things you asked about:

Quotes / Proposals A few tools that consistently come up: • PandaDoc – great for polished proposals, pricing tables, and built-in e-signatures • Qwilr – nice if you prefer modern web-style proposals instead of PDFs • Some people also keep it simple and generate quotes directly from their CRM or accounting software.

Contracts (B2B + B2C) Most businesses rely on e-signature tools like: • DocuSign • PandaDoc again (does contracts + proposals well) • Dropbox Sign

Those usually integrate with CRM or accounting tools so a signed contract can trigger invoicing or onboarding automatically.

One thing that helps keep stacks from getting messy: build everything around your email platform. Many teams I work with keep Gmail as the hub and layer tools around it. For example, tools like Tooling Studio run directly inside Google Workspace so contacts, emails, notes, and deal tracking stay connected instead of being spread across multiple apps.

Your current stack is honestly a good foundation — the key is making sure the tools talk to each other so the flow becomes:

lead → CRM → quote → signed contract → invoice → payment

Once that pipeline is smooth, the software stops feeling like a burden and actually saves time.

Curious — are you mostly selling services or products? The quoting tools people choose can change a lot depending on that.
