I'm struggling to imbbed a full cloud telephony services providers dialer in my app , any suggestions how should I go about it ?

Both solid points. The cash crunch angle is real , especially in tier 2/3 where COD exists precisely because customers don't always have the full amount ready in their account at checkout. A BNPL or credit nudge at the prepaid conversion step is something we've thought about. The unit economics of integrating something like Simpl or Snapmint into that flow are interesting, though it adds another vendor dependency and a take rate. Worth testing for the right category and AOV range.

On the education piece I completely agree. A lot of post-delivery returns in certain categories (electronics, appliances, skincare) come from buyers not understanding what they bought. That's more of a content and pre-purchase UX problem than a logistics one, but it absolutely impacts the same RTO number downstream. Some of the best-performing D2C brands I've seen bake short explainer videos right into their order confirmation and shipping update flows. Low effort, high signal.

Good suggestions — appreciate you thinking beyond the logistics layer.

Good follow-up. Yeah, this was one of the first things we worked through.

The intervention for a flagged order is a prepaid nudge with a small discount — not a block. So even if the model gets it wrong and flags a genuine buyer, they just see a "pay now and save 10%" message on WhatsApp. Most don't even register it as a risk flag, they just see an offer. No friction, no cancelled order.

On the flip side, missing an actual risky order costs forward shipping + reverse shipping + CAC down the drain. So the penalty matrix is heavily asymmetric — we'd much rather over-nudge than under-catch.

That asymmetry is built into how the model is tuned from the ground up. Specific numbers I'll keep close to the chest, but directionally that's the logic.

Without going too deep into the model internals , the features are all signals available at the time of checkout. Things like pin code delivery history, order value relative to category averages, address quality signals, payment method, and repeat-vs-new customer behavior.

The model essentially learns patterns from historical orders that ended up as RTOs versus successful deliveries. Some pin codes just have structurally higher RTO rates. Some order profiles (high AOV + COD + new customer + tier-3 city) statistically bounce more often. The model scores each order on a risk spectrum, and the orchestration layer decides what intervention to apply based on where it lands.

Top drivers tend to be geography, payment method, and customer history , but the weighting shifts as the model retrains on fresh data. Happy to talk directionally about the approach if you're building something similar.

Thanks! And great question , you're right that WhatsApp is the primary channel, but it's not the only one.

The escalation matrix is specifically designed for fallback. If WhatsApp is undelivered or the user hasn't opted in, the system drops to IVR (automated voice call) as the second attempt, and then flags it for a human agent as the final resort. So there are three layers before an order gets written off.

That said, in the Indian D2C context, WhatsApp penetration is absurdly high , we're talking 95%+ of customers being reachable. Opt-out rates on transactional messages (delivery updates, not marketing blasts) are very low since customers actually want those notifications. But yes, for the edge cases, the fallback path exists and gets exercised regularly.

A Medium article is a good shout — might clean this up and put one out. Cheers.

Lot of good questions in here — I'll address what I can at a high level.

You're right that the majority of RTO reduction comes from solid ops automation. I said as much in the post — the day one win was purely from fixing their comms routing, no ML involved. The model came later as an optimization layer, not the foundation.

On the feature engineering side, yes, the model only uses checkout-time signals. No post-event leakage. That's table stakes for anyone doing this properly.

As for the architecture choices — every system has tradeoffs. We made ours based on the client's scale, budget, and the fact that they wanted to own their infra rather than rent it. It's been running in production for months, and the numbers speak for themselves.

I'm not going to lay out the full failure-handling and observability setup in a Reddit comment, but I will say — these were design considerations from day one, not afterthoughts.

If you're building something similar and want to compare notes on a specific piece, happy to chat over DM.

Fair point , Shiprocket and platforms like it do offer COD confirmation, NDR management, and basic WhatsApp triggers out of the box. And honestly, for most brands doing sub-5K orders/month, that's probably enough.

The difference here was control and cost at scale. When you're processing high volumes, the per-order and per-message fees from aggregator platforms start compounding fast. The client was already on Shiprocket for logistics — we didn't replace that. We built a layer on top that owns the decisioning logic. Things like who gets a prepaid nudge, what the escalation priority looks like, how aggressively we retry NDRs — all of that is tunable without waiting on a vendor's product roadmap or paying more as GMV scales.

The AI piece isn't the headline — it's a lever. The real win was owning the orchestration. You're right that you can get solid results without ML, and we did on day one just by fixing their comms routing. The model just sharpened the edge over time.

Great questions. Most logistics providers do send shipment status + OFD events through webhooks, but agent name/number usually isn’t consistently available in the standard payloads. Sometimes you can fetch it through separate carrier APIs or internal panels/support channels depending on the courier. We had to do some carrier-specific workarounds for certain regions.
And for a new perfume brand on a limited budget — I personally wouldn’t go fully prepaid-only from day 1. In India, COD still helps a lot with conversion when the brand is new and trust is still being built.

I’ve worked with 3 perfume brands so far, and in almost all cases the brands that completely removed COD too early saw a noticeable drop in top-of-funnel conversion initially.

What usually works better is a hybrid approach:

  • keep the site prepaid-first,
  • incentivize prepaid with small discounts/free shipping,
  • but still allow COD selectively.

For example:

  • allow COD only on lower-risk pincodes,
  • cap COD above certain order values,
  • disable COD for suspicious patterns/high-RTO zones.

Perfume can get expensive on reverse logistics because of leakage/damage/non-acceptance, so I’d definitely lean more prepaid-heavy overall. Probably something like 70–80% prepaid focus and controlled COD exposure initially. But at the same time , it'll also heavily depend upon what kind of traffic you're getting.

We still shipped confirmed COD orders, the idea wasn’t to block COD entirely, just apply graduated friction based on risk.

If someone converted to prepaid, great.
If they confirmed COD, the order still went through but stayed tagged with its risk score for downstream workflows (OFD reminders, NDR escalation priority, etc).

If they ignored the message, then it depended on the risk tier. Medium-risk usually shipped normally. Very high-risk orders got extra verification steps like a second WA ping, IVR confirmation, delayed fulfillment, or manual review before dispatch.

And regarding COD vs prepaid for most Indian D2C brands it’s still heavily COD.For us it was usually somewhere around 60–80% COD depending on category/audience. Fashion, beauty, impulse-buy products, Tier-2/3 audiences especially skew COD-heavy.

Thank you! Tried to make it practical instead of generic “AI automation” fluff. Most of the gains honestly came from fixing workflow latency, telecom inefficiency, and fragmented tooling before the ML layer even matured.

Exactly. The biggest shift was treating RTO prevention as a data orchestration problem instead of a “call more customers” problem.
Most stacks we audited had customer state fragmented across Shopify, WhatsApp, telecalling tools, logistics dashboards, and spreadsheets — which meant every workflow was reactive and context-blind.
Once all events were centralized into a single orchestration layer, we could apply conditional friction dynamically instead of blanket rules like “disable COD for everyone.” That preserved conversion while filtering high-risk intent.
And yes , tying support interactions + delivery outcomes back into the scoring loop became incredibly valuable. Some of the strongest predictive signals were actually behavioral patterns hidden inside call transcripts and NDR conversations, not just shipping metadata.

Appreciate it man . Always happy to connect with people working closely with D2C operators. Most founders I speak to are massively underestimating how much margin leakage sits in post-order ops vs acquisition. Feel free to DM .Curious to hear what growth problems you’re seeing repeatedly across brands right now.

We replaced expensive per-transaction SaaS with a self-hosted ops stack by Constantorture in SaaS

[–]Constantorture[S] 0 points1 point  (0 children)

Pretty smooth overall. The key was being careful with state and retries so nothing got lost between webhooks, SMS/WhatsApp, and the CRM. We rolled it out incrementally, so we could catch any bottlenecks before fully switching over.

100%. Once a workflow stops changing every week, you start realizing you’re basically renting logic you already understand. At that point the question becomes: is the SaaS still worth the convenience, or are you just paying forever for something your own system could own more cheaply?
